AT TORNEY Patented June v2, 1931 PATENT OFFICE LOUIS BORTEN, OFPHILADELPHIA, PENNSYLVANIA VALVE CONSTRUCTION Application filed March30, 1929. Serial No. 351,252.

This invention relates to' float valves for controlling the inflow ofliquid to a receptacle as a flush tank associated wit-ha water closet.

-An object of the invention is to improve L1 constructions of thischaracter. I

A further object 'is to provide an inflow pipe and valve so constructedand related as to insure a positiveand complete closing of the valve onits seat.

A further object is to provide a float valve construction all of thedamagable parts of which are readily accessible and easily renewed.

The above objects are accomplished by providing an inflow pipe having aspout extending therefrom and preferably bent downward at its outer end.An external valve is provided for closing the open end of the spout andsaid valve is in turn controlled by a float in any suitable manner, onemanner being by attaching the float to an arm which is pivoted to astationary member, as to the inflow pipe, upon which the valve member,which may be in the nature of a disk of yieldable material, is mountedin such position that when the liquid inthe tank rises to a certainlevel, the valve will be closed against the end of the spout and inorder that a positive closing of the end of the spout by the valve maybe insured, the spout may be formed with a circumferential bead whichwill contact with and somewhat depress the material of the valve whenthe said valve is pressed against said bead. The disk may be held inposition by a flanged annular member secured to the arm and the disk maybe removed and renewed whenever, for any reason, this may be desired.

In the drawings:

Figure 1 is a section through a tank showing the inflow pipe and theassociated valve constituting the subject of my invention.

Figure 2 is a vertical section through the inflow pipe showing therelation of the valve to the spout.

Figure 3 is a detail perspective view showing the beaded discharge endof the spout.

Figure 4 is a detail plan view of the valve carrying arm showing themounting of the valve disk thereupon.

'opensor close the end of the spout 12 as the suitabletool', as a pairof pliers.

Referring to the drawings by reference numerals, 10 designates a tank ofthe type commonly known as a flush tank and 11 des-v lgnates the inflowpipe associated therewith,

12 is a spout extending therefrom and hav mg a down curvature toward itsouter end.

13 is a pivoted arm upon whicharvalve construction 14. is mounted inposition to be brought againstthe end of the spout 12 when the level ofthe fluid in theitank rises to a certain predetermined level.

The inflow pipe 11 is provided with a central' bore 15, which.communicates with the bore 16 o-f-the spout 12 providing a continuouspassageway to the end of said spout. A 65. bracket 17 is provided on theinflowpipe and extends at right angles thereto and to this bracket ispivotally secured an arm 18 by means of the pivot pin 19 which isextended through a loop 20 in the end'of the 7 bracket 17 and throughapertures in spaced members 21 secured to the arm 18. These spacedmembers constitute a support for the valve constructionwhich consists'ofa cup like member 22 soldered or otherwise secured to the spaced membersand'having a closed bottom and a circumferential flange23 at its upperedge. I

Within the cup-like member ismounted a disk-like member 24 which may bein the nature of a washer of yieldable or resilient ma terial as fibre,rubber or the like. Cooperat ing with this disk andextending from theend'of the spout is a head 25 extending cir-V cumferentially of the endof the spout. The

arm 18 is provided at its free end "with a.

float 26, which, under the influence of the change of level in theliquid in the tank, will case may be. r

, The pin .19 is of a construction to be readily removable, beingslightly. tapered from one end to the other and at the smaller end.being provided with a kerf 27 so that the legs formed thereby may bebent in opposite directions to preventdislodgmentof the pin underordinary stresses; the pin, however, being -removable under a.comparatively slight force or by a-pull thereupon with a Attention is tobe called to the fact that the parts of the valve construction lie onthe outside of the intake pipe and are readily accessible to anattendant for regulation of the same. The washers 24 are readilyremovable and replaceable and in case the arm or the space membersattached thereto should become mutilated or'worn or should otherwise getout of commission the pin 19 may be readily removed in the above mannerand the whole valve construction replaced or repaired as the case maybe. The arm 18 is threadedly connected with the spaced members as shownat 28 so that these parts may one be renewed without the renewal of theother whenthis may become desirable.

The apparatus illustrated may be modified or'changed in various wayswithin the scope of the invention herein set forth and I do 2m not wishto be limited in the scope of the invention except as I shall be limitedby the appended claims; r
